He's President Obama's pick to fix the Department of Veterans Affairs, a graduate of West Point and the former CEO of one of the country's largest companies. And Tuesday, Robert McDonald found himself before a Senate committee for confirmation.

"The VA is in crisis. The veterans are in need. There is much to do. But I can think of no higher calling,” McDonald said.

Some question why McDonald would want take on such a tough role in the wake of scandal.

"It's tough to envision why anybody would take this job,” said Sen. Richard Burr, R-N.C.

"You don't need this job,” said Sen. Bernie Sanders, I-Vermont. "Why do you want this job?"

"I desperately want this job because I think I can make a difference,” McDonald said.

The Ohio businessman says making a difference starts with a fundamental change in how the VA holds itself accountable.

"I will put the veteran at the center of everything that we do, consistent with our mission,” he said. "Those employees that have violated the trust of the nation and of veterans must be and will be held accountable.”

McDonald also told lawmakers he’s committed to improving technology and communication within the agency and recruiting top level talent.

With virtually no opposition to McDonald’s nomination, some expect he could be sworn in as Secretary of Veterans Affairs before Congress takes its August recess next month.
